Support rev in PUT URL
----------------------

                 Key: COUCHDB-642
                 URL: https://issues.apache.org/jira/browse/COUCHDB-642
             Project: CouchDB
          Issue Type: New Feature
          Components: HTTP Interface
         Environment: trunk 08 Feb 2010
            Reporter: Brian Candler
            Priority: Minor


A DELETE request lets you append ?rev=xxxx to the URL. But this doesn't work 
with a PUT request; you have to put the _rev in the body instead (even though 
the _id is taken from the URL path)

$ curl -X PUT -d "{}" http://brianadmin:brianad...@127.0.0.1:5984/briantest/foo
{"ok":true,"id":"foo","rev":"1-967a00dff5e02add41819138abb3284d"}

$ curl -X PUT -d "{}" 
http://brianadmin:brianad...@127.0.0.1:5984/briantest/foo?rev=1-967a00dff5e02add41819138abb3284d
{"error":"conflict","reason":"Document update conflict."}

$ curl -X PUT -d '{"_rev":"1-967a00dff5e02add41819138abb3284d"}' 
http://brianadmin:brianad...@127.0.0.1:5984/briantest/foo
{"ok":true,"id":"foo","rev":"2-7051cbe5c8faecd085a3fa619e6e6337"}

Allowing ?rev in the URL would make PUT and DELETE more consistent, and would 
allow you to replace an existing JSON doc with another one without having to 
merge the _rev into it first.
